Abstract

PURPOSE:To prevent a card from being illegally used by the time-up of timers when a card and a personal identification processor are not operated for a fixed time by providing the card and the processor with respective timers. CONSTITUTION:When the use of a card 10 is started, identification(ID) data are inputted by a user. When the ID data are correct, the card 10 is set up to a usable state. After setting up the usable state of the card 10, a card 10 is loaded to the personal ID processor 20 and the processor 20 is operated. When the card side timer 14 is turned to the time-up state after setting up the card 10 to the usable state, the card 10 is turned to its unusable state. Only when the card 10 is in the usable state, the card 10 can be loaded to the personal ID processor 20. When the usable card 10 is loaded, the processor side timer 14 restarts clocking, and when the timer 14 is turned to the time-up state, the operation of the processor is finished.

If the card-side timer times up, the card becomes unusable. Therefore, a card left unused for a certain period of time cannot be used by a third party. Furthermore, if the timer on the device side times up, the operation of the device ends and becomes unusable. Each time the operating section is operated, both timers restart timing, so if the device is not operated for a certain period of time or more, the device timer times out, the device stops operating, and becomes unusable. This prevents unauthorized use of both the card and the device.

再入力指示が行なわれる（ステップＳ３）。First, when the use of the card is started, the user inputs identification data (step S1), which is as follows.
This is done using the data input means 12. Next, it is determined whether the identification data is correct (step S2). This is executed by the identification data matching means 13. Here, if the identification data is correct, the process moves to the next step S4, but if the identification data is incorrect, a re-input instruction is normally given several times (step S3).

ような処置が行なわれる。ステップＳ３における再入力
指示処理は、このような処理を含むものとする。However, if incorrect identification data is entered a certain number of times or more, it is regarded as fraudulent use, and measures are taken to prohibit the use of the card. It is assumed that the re-input instruction processing in step S3 includes such processing.

装着して装置の操作を行なうことができる。When the correct identification data is input, the card is set to a usable state in step S4. This is executed by the card control means 11. After that, the data stored on the card can be read using the key provided on the card, but after making the card usable in this way, The device can be operated by attaching it.

Step S2). If the card is not available, the device terminates operation. In this case, there is no problem in returning to the state before the card was inserted.

If the device-side timer 24 has not timed up, it is determined whether or not there is a transaction operation. This depends on whether or not the operation unit 22 has been operated. Each time the operation unit 22 is operated, step S is performed.
3, and the device-side timer 24 and card-side timer 14 start counting again. That is, both are returned to their initial state,
You will have to start counting again from the beginning.

題はない。Furthermore, in this embodiment, since the device-side timer 24 and the card-side timer 14 are restarted each time a transaction operation is performed, the time until the card-side timer 14 times out is the same as that of the device-side timer 24. It must be set longer than the time until time-up. Otherwise, the card side timer 14 will time up before the device side timer 24 times up, and the card itself will become unusable. However, when the device side timer 24 restarts the time measurement and the card side timer 14 restarts the time measurement,
If you do it at your own timing, you won't have that problem.

れる。(Effects of the Invention) According to the identity verification processing method using a card of the present invention described above, after the card is made usable by inputting identification data, if the card is left unused for a certain period of time, it becomes automatically unusable. state and prevent unauthorized use. Furthermore, even if the card is inserted into the device and the device is being used, if the operating section is left unoperated for a certain period of time, a timer on the device side automatically ends the operation of the device. This prevents unauthorized use of the device. As a result of the above, the security of identity verification processing using a card is significantly improved.
